Detailed Implementation

[0034] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0035] See Figure 1 and Figure 2 As shown in the figure, an automatic wiring and disconnection device provided in this application embodiment may specifically include: a base plate 1, a cover plate 2, at least one bracket 3, at least one electrode pusher 4, and at least one electrode 5.

[0036] The base plate 1 specifically includes a base plate body 11 and a cover plate receiving area 12. The base plate body 11 is the supporting structure of the automatic wiring and disconnection device; in this application, the base plate body 11 can be rectangular. The cover plate receiving area 12 is disposed on the base plate body 11, combined with… Figure 2 As shown, the cover plate receiving area 12 has a hollow structure 121.

[0037] To facilitate the connection between the automatic wiring and disconnection device and the device under test, in a specific example, the base plate 1 also includes a device under test placement area 13. The device under test placement area 13 is located on one side of the cover plate receiving area 12, specifically on the right side of the cover plate receiving area 12 in this example.

[0038] The cover plate 2 specifically includes an integrally formed connecting part 21 and an opening / closing part 22. A piston rod connector 23 is provided on one side of the lower surface of the connecting part 21. The piston rod connector 23 has a pair of connecting ears 231, each connecting ear 231 having a first through hole (not shown in the figure), and the two first through holes are arranged opposite to each other. The opening / closing part 22 is provided with at least one electrode inlet / outlet hole 221. The shape of the electrode inlet / outlet hole 221 can be rectangular or square, and the arrangement and number of the electrode inlet / outlet holes 221 can be determined according to specific needs. In this example, the number of electrode inlet / outlet holes 221 can be four, arranged in a straight line.

[0039] The cover plate 2 is housed within the hollow structure 121, with its connecting part 21 adjacent to the testing equipment receiving area 13, meaning the opening and closing direction of the cover plate 2 is opposite to the testing equipment 7. To ensure that the cover plate 2 opens and closes slowly and uniformly along the base plate body 11, the connecting part 21 of the cover plate 2 is pneumatically connected to the base plate body 11. This allows the opening and closing part 22 to automatically rotate up and down along the base plate body 11 with the side of the connecting part 21 as its axis. The pneumatic opening and closing connection can be achieved using a cylinder 10. The cylinder 10 includes a cylinder barrel 101 and a piston rod 102. The cylinder barrel 101 is located in the cover plate receiving area 12 and is fixed to one corner of the lower surface of the base plate body 11. The bottom end of the piston rod 102 is located inside the cylinder barrel 101, while the top end protrudes outside the cylinder barrel 101, and the top end has a second through hole (not shown in the figure). The top end of the piston rod 102 extends into a pair of connecting ears 231 of the piston rod connector 23. The second through hole is aligned with a pair of second through holes. The screw passes through the first through hole, the second through hole and the first through hole in sequence, so that the piston rod 102 and the piston rod connector 23 are hinged.

[0040] In a specific example, to ensure the stability of the connection between the cover plate 2 and the base plate 1, the connection between the cover plate 2 and the base plate body 11 also includes one or more of the following: snap-fit ​​connection, pin connection, button connection, and hinge connection. In this example, it is a hinge connection.

[0041] The bracket 3 is the main support structure for the electrode pusher 4 and the electrode 5, and is fixed to the lower surface of the cover plate 2. In a specific example, the bracket 3 includes a first support plate 31 and a second support plate 32. The first support plate 31 is located below the electrode inlet / outlet hole 221 and is fixed perpendicularly to the lower surface of the cover plate 2. One end of the second support plate 32 is connected to the first support plate 31, and the other end is fixed to the lower surface of the cover plate 2 at a certain angle. This creates a triangular structure between the bracket 3 and the cover plate 2, enhancing the stability of the bracket 3.

[0042] The electrode actuator 4 is one of the driving structures for achieving efficient wiring and disconnection. To save installation space, the electrode actuator 4 in this application can specifically be implemented using a magnetically coupled rodless cylinder. See [link to application]. Figure 3 As shown, the magnetically coupled rodless cylinder includes two support seats 41, a guide rod 42, and a slider 43. The two support seats 41 are respectively fixed to the first support plate 31, such that the electrode pusher 4 is perpendicular to the cover plate 1. The guide rod 42 is located between the two support seats 41. The slider 43 passes through the guide rod and can reciprocate along the guide rod 42. In this application, the number of electrode pushers 4 is specifically four.

[0043] One end of electrode 5 is fixed above slider 43, and the other end is aligned with electrode inlet / outlet hole 221, so that it can reciprocate along electrode inlet / outlet hole 221 under the drive of electrode pusher 4. In this application, the number of electrodes 5 is specifically four.

[0044] In an optional embodiment, the automatic wiring and disconnection device further includes a test equipment bracket 6. The test equipment bracket 6 includes multiple support beams 61 and multiple partitions 62. The multiple support beams 61 are arranged parallel and at equal intervals in the test equipment receiving area 13, and the multiple partitions 62 are fixed parallel and vertically to the upper surface of the support beams 61.

[0045] The above describes the composition and connection relationship of an automatic wiring and disconnection device provided in the embodiments of this application. The working principle is briefly described below.

[0046] See Figure 2 and Figure 3 As shown, when the automatic wiring and disconnection device is working, the cylinder 10 receives a first signal and pushes the piston rod 102 to move towards the cover plate 2. The opening and closing part 22 of the cover plate 2 rotates clockwise along the base plate body 11, causing the bracket 3, electrode pusher 4, and electrode 5 to rotate until the cover plate 2 and the base plate 1 are at right angles. The electrode pusher 4 receives a second signal and drives the electrode 5 located above the slider 43 to move through the electrode inlet and outlet hole 221 towards the device under test 7 until the electrode 5 is connected to the terminal 71 of the device under test 7.

[0047] See Figure 1 As shown, when the automatic wiring and disconnection device finishes working, the electrode pusher 4 receives a third signal and drives the electrode 5 to move away from the device under test 7 along the electrode inlet / outlet hole 221. The cylinder 10 receives a fourth signal and pulls the piston rod 102 to move away from the cover plate 2. The opening and closing part 22 of the cover plate 2 rotates counterclockwise along the base plate body 11, and drives the bracket 3, electrode pusher 4 and electrode 5 to rotate until the upper surface of the cover plate 2 is parallel to the upper surface of the base plate body 11. The cover plate 2 closes, and the first support plate 31 of the bracket 3, the electrode pusher 4 and electrode 5 are perpendicular to the base plate body 11 and are protected under the cover plate 2.

[0048] This application provides an automatic wiring and disconnection device. Through the pneumatic opening and closing connection between the cover plate and the base plate, the cover plate can automatically rotate up and down along the base plate, driving the bracket fixed on the cover plate to rotate up and down, thereby driving the electrode pusher and electrode located on the bracket to rotate up and down. The slider of the electrode pusher reciprocates along the axial direction of the electrode pusher, which can drive the electrode to connect or disconnect with the wiring terminals of the device under test along the electrode inlet and outlet holes, thereby realizing automatic wiring and disconnection with the device under test, saving testing time and improving testing efficiency.
